METALLlC CALKlNG-STRlP.

SJPEGIFKCATION forming part of Letters Patent No. 491A17, dated February7, 1893.

Application filed July 20, 1892 Serial No. 4 ,7 (N m l-l To aZZ whom itmay concern;

Be it known that I, FRANCIS W. FINCHER, a citizen of theUnited States,residing at Pentwater, in the county of Oceana, and in the State ofMichigan, have invented a new and useful Metallic Oalking-Strip, to heused in stopping the seams of boats and vessels of different sizes andthickness of planking; and I do declare that the following is a full,clear, and exact description of my invention, reference being had to theaccompanying drawings, formiuga part of this specification, which willenable others skilled in the art to which it appertains to make and usethe same.

My invention consists of a metallic strip, having a tongue portionadapted to be inserted into the seams of boats and secured thereinsubstantially as hereinafter described.

The metallic boat calking is intended to be used instead of oaknm andcotton commonly used for stopping seams of boats, and is described asfollows, reference being had to the accompanying drawings.

Figure lillustrates one form of my metallic calking strip. Fig. 2.illustrates por tions of two planks shaped to receive the calking stripshown in Fig. 1. Fig. 3. shows the calkiug strip secured to theplanking.

Referring to the construction shown in the drawings; a designates themetallic calking strip which in this instance is to be made of sheetcopper, zinc or other desirable metal, folded upon itself from bothsides forming a flange portion a", and where meeting at the center oftlieflange both portions being bent outward forming a tongue portion aThe planks b. I). see Fig. 2. are formed with rabbets or grooves Z). Z).on both outer edges to receive the flanges. lhe planks also have groovesor rahloets b Z2 at their inner edges for a purpose to he presentlyexplained.

In applying this form of calking strip the tongue a is inserted throughthe joint between the planks and the two parts of the tongue areseparated and turned outward and secured in the rabbets 12 by nails orrivets c. 0.

Small row or sail-boats are usually built lap streak or clinkerpatternand with the metalliccalking as shown in Fig. 1, a boat with asmooth surface, or outside, can be built stronger, and as light asdesired; the planks all hein g fastened together with the metalliccalking; and permits the boats planking to shrink and swell Withoutloosening the calk- The use of the metallic calking overcomes adifficulty often met with when the usual oakum or cotton is used; inthat; it will not be pulled out When left in the ice during the Winter.

The metallic calking will greatly protect the boat and keep it fromchafing and the boat will never require recalking when once calked withthe same.

Having fully described my invention: What I claim and desire to secureby Letters Patent is A means for stopping the seams of looats consistingof a strip of sheet metal doubled upon itself from its sides toward thecenter, thence at a right angle forming a flange portion and a tongueportion, said tongue portion adapted to be inserted into the seam of aboat, then turned outwardly forming an inner flange, said flangesadapted to be received in rahbets in the outer and inner edges of theplanks, and to be secured therein substantially as described.
